About Last Phase #6

Open slonyarakmw opened 3 years ago

slonyarakmw commented 3 years ago

Hi, i doesn't programmer, and english is not my native language, but i find some hints in the path "SalPhaselon". It can be obviously, but i cant stop tell about it. And this is interesting. :)

We have different styles of letters and 2 fragments with only "a" and "b" letters. if we decode a=0 , b =1, we'll get : "matrix sum list" And word - "enter" which located after non encrypted phrase: "fourfirsthintisyourlastcommand". And in the end we have also non encrypted phrase: "fans too".

Atleast whole picture is like this: d b b i b f b h c c b e g b i h a b e b e i h b e g g e g e b e b b g e h h e b h h f b a b f d h b e f f c d b b f c c c g b f b e e g g e c b e d c i b f b f f g i g b e e e a b e

matrixsumlist

It seems that path which starts with "U2FsdGVkX" is Base64 code (means "Salted") And what can does matter "abe" in the end of parts?

What are you thik about it ?

shinnida220 commented 3 years ago

I was looking through this additional hints yesterday I and found this our first hint is your last command - Making me wonder, what was the first hint the creator gave - the picture, the rabbit or what? If we can know the exact first hint, i bet it will lead us somewhere

i was going to open an issue as a discussion when I found your talk. Thanks for posting this. I understand your english is not very clear but I cannot really understand the wording and how you arrived at the text above.

I mean the abe and others. Can we review this together

slonyarakmw commented 3 years ago

If i understand you right... "abe" just stand out from others (this is just my guess). matrix sum list - is appeare from fragment of text:

a b b a b b a b a b b a a a a b a b b b a b a a a b b b a a b a a b b a b a a b a b b b b a a a a b b b a a b b a b b b a b a b a b b a b b a b a b b a b b a a a b b a b a a b a b b b a a b b a b b b a b a a

i'm just had seen, that in this fragment we have only "a" and "b" letters.. and i think to decode this like binary code if a=0, and b=1; we'll get: 01101101011000010111010001110010011010010111100001110011011101010110110101101100011010010111001101110100 and then we decode this in to ASCII. and get: matrixsumlist

and also we get if decode fragment below: a b b a a b a b a b b a b b b a a b b b a b a a a b b a a b a b a b b b a a b a 0 1 1 0 0 1 0 1 0 1 1 0 1 1 1 0 0 1 1 1 0 1 0 0 0 1 1 0 0 1 0 1 0 1 1 1 0 0 1 0 ASCII : enter

shinnida220 commented 3 years ago

I looked up abe, its some form of cryptographic encryption. Link here Who knows maybe all the parts with a b e after are encoded using the said encryption function

edoardocoen commented 3 years ago

I think you must have max 64 characters for line to decrypt messages, this is why there is enter after the first 64 char... and i think it is shabe non abe, if you stop at shabe you have another 64 characters:

another thing is that here f a e d g g e e d f c b d a b h h g g c a d c f e d d g f d g b g i g a a e d g g i a f a e c g h g g c d a i h e h a h b a h i g c e i f g b f g e f g a i f a b i f a g a e g e a c g b b e a g f g g e e g g a f b a c g f c d b e i f f a a f c i d a h g d e e f g h h c g g a e g d e b h h e g e g h c e g a d f b d i a g e f c i c g g i f d c g a a g g f b i g a i c f b h e c a e c b c e i a i c e b g b g i e c d e g g f g e g a e d g g f i i c i i i f i f h g g c g f g d c d g g e f c b e e i g e f i b g i b g g g h h f b c g i f d e h e d f d a g i c d b h i c g a i e d a e h a h g h h c i h d g h f h b i i c e c b i i c h i h i i i g i d d g e h h d f d c h c b a f g f b h a h e a g e g e c a f e h g c f g g g g c a g f h h g h b a i h i d i e h h f d e g g d g c i h g g g g g h a d a h i g i g b g e c g e d f c d g g a c c d e h i i c i g f b f f h g g a e i d b b e i b b e i i f d g f d h i e e e i e e e c i f d g d a h d i g g f h e g f i a f f i g g b c b c e h c e a b f b e d b i i b f b f d e d e e h g i g f a a i g g a g b e i i c h i e d i f b e h g b c c a h h b i i b i b b i b d c b a h a i d h f a h i i h i c z a g d a f a o a h e i e c g g c h g i c b b h c g b e h c f c o a b i c f d h h c d b b c a g b d a i o b b g b e a d e d d e z c f o b f d h g d o b d g o o i i g d o c d a o o f i d h z s h a b e

we can find "z" and "o" only in the end and before this, we have only the fist 9 characters of the alphabet. This section start and finish with "z, just before "shade". If you count characters starting from the first z to the second one, we have 64 characters too

  1. So we need to decode this salted string.
  2. We have a some hint matrixsumlist
  3. Then the hint - our first hint is your last command

I broke down the whole string into this..

Whao! 9ce one, thanks.

I've tried a possible combination of sha256 - no luck I put together a couple of functions (from stackoverflow) to add up the matrix and i got this - 100110001001.

My though is sha256 of somewords/a word will be used to descrypt the salted string

similar to abba translation except using hex and: z=string terminator o=0

but as far as I can tell, it doesn't help with the rest of the phase

I looked at this for quite a while last year, but the best I can find with the qr is that it's a result of the image compression

As for the single square that's a different color, that's still an open mystery

Just convert letters to digits, a -> 1, b -> 2, ..., o -> 0 to make a big 10-base integer and convert it to string.

Base34?
